STARTING MECHANISM FOR INTERNAL-COMBUSTION ENGINES.

Specification of Letters Patent.

Application filed August 8, 1910.

Patented Aug. 22,

Serial No. 576,212.

To all whom it may concern:

Be it known that I, CHARLES A. DEAL, a citizen of the United States ofAmerica, residing at Los Angeles, in the county of Los .-\ngeles. Stateof California, have invented a certain new and useful Starting Mechanismfor Internal-Combustion Engines; and I do hereby declare the followingto be afull,

- clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to starting mechanism for internal-combustionengines, and it has for its objects to'provide a novel constructiontherefor which shall be easy and convenient to manipulate, strong anddurable in use, positive and effective in action, and by which isavoided danger of injury to the operator in case the engine operates torotate he crank shaft in a reverse direction.

With the above and other objects and advantages in view which will beapparent to those skilled in the art, the invention may be said toconsist of the novel construction, arrangement and combination of partsas set forth in the claims and as will appear from a consideration ofthe description hereinafter of two preferred forms of construction inwhich the invention may be einbodied, the. construction beingillustrated in the accompanying drawings forming part hereof, of whichdrawings- Figure 1 is a plan view of one form of construction for theinvention in connection with the gas engine. Fig. 2 is a partly brokenaway elevation of-the construction shown in Fig. 1. on the line X"-X-"of Fig. 1, the pawl being in changed position. Fig. 4 is a section takenon the line X X of Fig. 3. Fig.

-5 is a section taken on the line X--X of Figs. 1 and 6. Fig. 6 is apartial detail of the ball clutch, and Fig. 7 is a modified construction for a portion of the actuating mechanism.

On the crank shaft 2 of an internal combustion engine, indicated by thenumeral 3 inFigs. 1 and 2, may be mounted a. device 4 connected withactuating mechanism for turning the crank shaft to start the engine; thedevice being adapted to be disengaged from the actuating mechanism afterthe engine starts. As shown in Figs. 1, 6 and 7, the de ice 4 maycomprise the sprocket Fig. 3 is a section taken rigidly mounted on thecrank shaft and recessed to receive the disk 8 having the inwardlyinclined recesses 9 on the periphery thereof in each of which recessesis disposed a ball 10. A plate 11 is secured to the disk 7 to retain theballs 10 in place in the recesses 9; and the plate together withthe'disk 7, sleeve 6 and sprocket wheel 5 are loosely mounted on thecrank shaft 2.

In one form of the construction for the actuating mechanism as shown inFigs. 1 to 4 inclusive, the hand lever 12 is secured to a shaft 13mounted on the bearings 14 on a suitable frame 15, and the shaft carriesfast thereto the segmental gear-wheel 16 which meshes with a rack bar 17adapted t0slide in the guideway 18 thereunder. In mesh with the rack bar17 is the pinion 19 secured to the disk 20 carrying the spring pressedpawl 21; the pinion 19 and the disk 20 being loosely mounted on theshaft 22 which is mounted in the bearings 23 and has fast thereon theratchet wheel 24 and the bevel gear wheel 25. The gear wheel 25 is inmesh with the gear wheel 26 fast on the shaft 27 which is mounted on thebearings 28 at each end thereof and carries the sprocket wheel 99 whichis connected with the sprocket wheel 5 by the sprocket chain 3 A stop 31connected to any suitable stationary part (not shown) prevents movementof the lever 12 to the left beyond the vertical position. The abutment32 secured to the fr 'ne is adapted to throw the pawl 21 out ofengagement with the ratchet wheel in consequence of the heel 33 of thepawl striking thereagainst at the limit of movement of the levcr tothe'left in the drawing.

\Vith the construction as above described and assuming that the lever 12occupies a position to the right of the vertical position, the operationmay be as follows: The lever on being moved quickly to the verticalposition rotates the shaft 13 and in consequence the segmental gearwheel 16 moves the rack bar 17 to the right to rotate the pinion 19 andthe disk 20 carrying the pawl 21 which, by means of the spring 34, ispressed in engagement with the ratchet wheel 24 so that the latter iscaused to-rota'te with the disk 20 and thereby rotate the shaft .22 andalso the bevel gear wheel 25 which through bevel gear wheel 26 drivesthe shaft 27 and the sprocket wheel 29 which by means of mechanism.

sprocket chain 30 drives the sprocket wheel 5 which thereupon actuatesthe ball "clutch to engage to turn the crank shaft to start the engine.

By thetime the lever reaches the stop 31, the pawl 21 will strike theabutment 32 and thus be thrown out of engagement with the ratchet wheel24 to disconnect the latter, the disk 20, pinion 19, rack bar 17segmental gear'wheel 16, shaft 13 and lever 12 from the remainder of theactuating Should the engine start the ball clutch becomes disengaged bythe balls as just moving to a lower position in the recesses 9, as willbe understood. In case the engine does not start after movement of thelever described the lever may be moved to the right and then quickly tothe left again and this operation repeated as many times as may benecessary to cause the enright, the segmental gear In moving the leverto the wheel 16 moves the rack bar 17 to the'left and the latter rotatesthe pinion 19' and disk 20, but the pawl 21 rides over the teeth of theratchet wheel 24 so that the remainder of the actuating mechanism is notafiected by such gine to start;

movement of the lever. I

In the form of construction shown in Fig. 7, the lever 12 carries theintegral bevel geared sector which meshes with the bevel p1nion36 onshaft 37. The pinion 36 is conpawl the nected by sleeve 38 with the disk39 carrying pinion 36, sleeve 38 and disk 39being loosely mounted on theshaft 37 and the pawl being associated'with a ratchet wheel 41 fast onthe shaft 37 The shaft 37 also has mounted fast thereon the sprocketwheel 42 which may drive by means of a struction, lever 12 being movedto the left sprocket chain (not shown) the parts shown in Fig. 1 on thecrank shaft 2. An abutment 43 is arranged adjacent to the ratchet wheel42, the abutment and also the disk- 39, pawl 40-and ratchet wheel 41 aresimilar to those already described in connection with the first form ofconstruction for the actuating mechanism. I I

In the operation of the last. form of concauaes the bevel geared sector35 to rotate the "bevel pinion and disk 40 and conse-' quently the shaft37 to drive the sprocket P wheel 42 because the pawl 40 is engaged withthe ratchet wheel 41. When the lever 'is near the vertical position thepawl40 strikes the abutment 43 and is disengaged from the ratchet wheel41 and thereby, the

' disk 39, pinion 36 and bevel geared sector 35 are disengaged from theremainder of the actuating mechanism as will be under-' In moving thelever to the right the bevel'geared sector 35 will rotate the pinion 36and disk 39 but the pawl will ride over the teeth of the ratchet wheel41 so that this patent may be obtained for five cents each, byWashington, D.
